IMPROVEMENT IN STOVES.

Specification forming partof Letters Patent No. 40,073, dated September22, 1863.

To all whom it may concern.-

Be it known that I, WILEY S. WRIGHT, of St. Louis, in the county of St.Louis and State of Missouri, have invented a new and useful Improvementin Sliding Doors for Stoves and Furnaces; and I do hereby declare thatthe following is a full, clear, and exact dC scription thereof,reference being had to the accompanyin g drawings, making a part of thisspecification, in which- Figure 1 is a front view of the front plate ofa stove having my improved sliding doors applied to it. Fig. 2 is a viewof the opposite side of Fig. 1, showing one of the doors in dotted linesthrown back. Fig. 3 is a vertical transverse section through the middleof Figs. 1 and 2. Fig. 4is a perspective view of the inside of one ofthe sliding doors.

Similar letters of reference indicate corresponding parts in the severalfigures.

The object of my invention is to construct and apply sliding doors tostove and furnace plates in such manner that the doors will work withless friction than hitherto, at the same time they will not be affectedin their perfect working by expansion and contraction, as will behereinafter described.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation,

The stove-plate A, to which the sliding doors B B are applied, is, inthe present instance, convex on its outer face, though it may be madeflat or concave if desired. Along the bottom of this plate A a roundedbead or molding, a, is formed, which serves merely as an ornament orfinish for the plate, but above the doors B B is a hollow ogee molding,b, which is riveted to the plate A, and forms a groove of a peculiarcharacter in which the upper projecting edge of the stove-doors slide,and by which they are retained in place.

The doors B B may he made plain,-or they may be ornamented in raisedwork, as shown in Figs. 1 and 3, and on the inside of each door, nearthe bottom of the vertical straight edge, I have formed ahook or finger,c, which hooks over and slides on the lower horizontal edge of the doorplate or frame, as shown in Figs. 2 and 3. These hooks c c are thus madeto form inner bearings for the doors B B,

which hooks receive the weight of the doors when they are closed orpartially closed, and while they thus supportthe inner ends of the doorsthey keep the lower edges of the doors in sutficiently close contactwith the doorplate A for all practical purposes, and do away with nearlyall friction, the bearingsurface of .these hooks being so very small,thereby causing the door to slide with freedom and ease at all times,much more so than where thebottom of the door slides in a groove, as instoves hitherto used. There being only one hook, c, on each door, andthese hooks being arranged at or near the inner or vertical ends of thedoors inside, it is necessary to support the outer ends when the doorsare closed or partially closed, and for this purpose the projections e con the outside face of the plate A, under the doors, are used, whichprojections are located at points directly under the outer ends of thedoors when the latter are closed, and, being very narrow, theseprojections cause very little friction. These projections c e arenotched to receive the lower edges of their respective doors before theogee molding b is applied, and when this strip is secured in its placeits lower edge projecting over the upper edges of the two doors, theyare prevented thereby from being moved out of their places.

By this mode of applying sliding doors to their frames it will be seenthat I obviate the objections to the grooves and other plans hithertoused, which cause the doors to bind and to work hard on account ofexpansion and contraction and friction.

My doors are supported upon the top edge of the lower part of thedoor-frame by narrow hooks or fingers, instead of in grooves formed insaid frame, and neither ashes, cinders, nor anything else can offerobstructions to them.

The door are moved back and forward by the thumb-pieees f f, and thestop-piece 70, shown in Fig. 3, prevents either one of the doors frombeing moved too far forward, while the hooks c 0 prevent the doors frombeing moved too far in the opposite direction.

The door-frame is notched at g g, as shown in Fig. 2, for the purpose ofallowing the hooks c c on the doors to enter these notches when thedoors are opened. These notches allow the doors to be opened to theirfull extent,

inside of the doors, substantially as and for the purposes described.

3. In combination with the inner hooks and outer supports, theoverhanging strip 1), applied to the door-frame, substantially as andfor the purposes described.

Witness my hand in the matter of my application for Letters Patent onimproved doors for stoves and ranges.
